Screen Snaper is perfect to quickly share a picture-perfect representation of anything on your screen.

First of all, let me say that this is my first gadget attempt and I have the intention to update this tool.

Do you remember Screen Snaper? It is the free tool that I created and for which most people asked me for the source code of the library SnaperHelper.dll.

Good news for you!

I am proud to present a new gadget version of this tool designed for Windows Vista SideBar and which includes all the source code.

Note: In this article, I will not explain all the code in detail.


Screen Snaper is a powerful, flexible and intuitive screen-capture utility. It allows you to capture anything on the screen.

  • Can capture full screen
  • Can capture Windows or objects on the screen
  • Can capture regions on the screen
  • Can copy image to clipboard automatically
  • Can automatically save captured images
  • Can save images in 7 popular formats: BMP/EMF/GIF/JPG/PNG/TIFF/WMF

Under the Hood

Basically ScreenSnaper is composed of three principal components:

  1. ScreenSnaperHelper (DLL)
  2. ScreenSnaperWrapper (COM)
  3. ScreenSnaper GUI (HTML)

ScreenSnaperHelper library encapsulates core capture function.

  • This is an API DLL written in MFC C++
  • Exposes <GetSnapType(eSnapType[CT_DESKTOP, CT_WINDOW, CT_REGION])>

ScreenSnaperWrapper library encapsulates core image manipulation function.

  • This is an COM DLL written in VB.NET
  • Exposes <GetSnap(eSnapType, eSnapMode[ToClipBoard, ToImage])>
  • Interface to ScreenSnaperHelper library between ScreenSnaper GUI.

ScreenSnaper GUI is the gadget interface itself.

  • This is an HTML page with some JavaScript and CSS
  • Create ScreenSnaperWrapper object to interface ScreenSnaperHelper

This can also be downloaded at Windows Live Gallery.
